<p>CORS（<strong>跨域资源共享，Cross-Origin Resource Sharing</strong>）目的是使用ajax实现可控的跨域访问。维基百科的解释为：CORS是一份浏览器技术的规范，提供了 Web 服务从不同网域传来沙盒脚本的方法，以避开浏览器的同源策略，是 JSONP 模式的现代版。与 JSONP 不同，CORS 除了 GET 要求方法以外也支持其他的 HTTP 要求。用 CORS 可以让网页设计师用一般的 <a href="https://zh.wikipedia.org/wiki/XMLHttpRequest">XMLHttpRequest</a>，这种方式的错误处理比 JSONP 要来的好。另一方面，JSONP 可以在不支持 CORS 的老旧浏览器上运作。现代的浏览器都支持 CORS</p>

<div class="paragraph">
<p>百度百科：在HTML5中新增了postMessage方法，postMessage可以实现跨文档消息传输（Cross Document Messaging），Internet Explorer 8, Firefox 3, Opera 9, Chrome 3和 Safari 4都支持postMessage。该方法可以通过绑定window的message事件来监听发送跨文档消息传输内容。</p>
</div>
<div class="paragraph">
<p>window.postMessage的功能是允许程序员跨域在两个窗口/frames间发送数据信息。基本上，它就像是跨域的AJAX，但不是浏览器跟服务器之间交互，而是在两个客户端之间通信。ge()方法允许来自不同源的脚本采用异步方式进行有限的通信，可以实现跨文本档、多窗口、跨域消息传递。</p>

<p>postMessage(data,origin)方法接受两个参数</p>
<div class="olist arabic">
<ol class="arabic">
<li>
<p>data:要传递的数据，html5规范中提到该参数可以是JavaScript的任意基本类型或可复制的对象，然而并不是所有浏览器都做到了这点儿，部分浏览器只能处理字符串参数，所以我们在传递参数的时候需要使用JSON.stringify()方法对对象参数序列化，在低版本IE中引用json2.js可以实现类似效果。</p>
</li>
<li>
<p>origin：字符串参数，指明目标窗口的源，协议主机端口号[+URL]，URL会被忽略，所以可以不写，这个参数是为了安全考虑，postMessage()方法只会将message传递给指定窗口，当然如果愿意也可以建参数设置为"*"，这样可以传递给任意窗口，如果要指定和当前窗口同源的话设置为"/"。</p>
